Alleged Ridgewood bomb-maker to appear in court Tuesday

A Ridgewood doctor who was arrested over the weekend and charged with amassing bomb-making chemicals is scheduled for a first appearance Tuesday in Central Municipal Court in Hackensack.

Authorities said they found a large amount of chemicals often used to make explosives at the home of Roberto Rivera. They also said they found assault rifles and other weapons.

Rivera was being held Monday at the Bergen County Jail on $1 million bail.

Rivera, 60, was described by acquaintances as being active in the Occupy Wall Street movement.

Ridgewood police showed up at Rivera’s home on Saturday on a hazardous-material report, Bergen County prosecutors said. The FBI and a county bomb squad later joined the search and found the weapons and chemicals, prosecutors said.

Rivera is charged with recklessly creating a risk of widespread injury, unlawful possession of a destructive device, unlawful possession of an assault firearm, unlawful possession of a large capacity ammunition magazine, and unlawful possession of a stun gun.
